TILE-KILN.

SPECIFICATION forming part of Letters Patent No. 426,732, dated April29, 1890.

Application filed December 12, 1889. Serial No. 333,545.

To all whom it may concern:

Be it known that I, HENRY MOEHLE, residing at St. Marys, in the countyof Auglaize and Stateof Ohio, have invented certain new and usefulImprovements in Tile-Kilns, of which the following is a specification.

My invention relates to a kiln especially (lesigned forburning tile; andit has for its oh- 3' ect to provide a kiln of this character whereindeflecting and burner walls are connectedwith a series of burnerspassing longitudinally through and into the kiln, and whereinburnerwalls are extended the entire width of the kiln transversely tothe burners, said burner-walls connected with the deflecting-walls, saidburners extending outside of main walls of kiln.

My invention consists in the novel construction and peculiar combinationof parts, all of which will hereinafter be fully described in theannexed specification, and particularly pointed out in the claims,reference being had to the accompanying drawings, in which Figure 1 is aperspective view of my improved kiln, parts being broken away to moreclearly illustrate the invention. Fig. 2 is a top plan view thereof.Fig. 3 is a vertical section of the same on the line 3 3, Fig. 2; andFig. 4 is a similar view thereof on the line 4 4, Fig. 2.

In the accompanying drawings, 1 1 indicate the side walls, and 2 2 theend walls, one side of the kiln having the usual door 3.

6 6 indicate a series of burners, which are fired from the outside ofthe kiln', and which extend across the bottom of the kiln andcommunicate therewith, as shown at 5 5. (See Figs. 1 and 2.)

9 9 indicate burners, also fired from the outside, which are arrangedabove the burners 6 6, and which extend a short distance into theinterior of the kiln, as shown, a floor-wall F being disposed betweenthe burners 9 and 6, said wall extended into the kiln and ending atvertically-arranged deflect-ing walls or chambers 7 7. The burners 6pass between a series of burner-walls H, which extend the full length ofthe kiln, between which transverse heatspaces I I are formed, whichcommunicate with the burners 6 6 at 5 5, and which serve to deflect theheat over the lower surface of the kiln,'and S 8 indicate ribs extendedover (No model.)

the inner end of the burner 9 9, which form heat-spaces 10 10, as shown.

By the above-described construction I am enabled to force the heat fromthe burners (3 through the heat-spaces I and equalize and distributesame over the bottom of the kiln,while the heat from the burners 9 9strikes against the walls 7 7, which extend entirely across the kiln,and is thereby deflected up through the heat-spaces 10, such spacesserving to more readily lead the said heat in an upward direction,thereby enabling me to get a heat near the outer walls of the kilnuniform with that in the center of the kiln, whereby I am enabled toburn a kiln of tile in forty hours,

whereas it usually requires seventy or eighty hours to burn a kiln inthe usual manner. By this construction I am also enabled to burn thetile all alike and sustain no loss in soft heat to pass up through thekiln, which beingopen at the top forms a draft or current,causing thesmoke and heat to rise, and thereby allowing me to build fires on theoutsides of the kiln and secure a complete combustion. The verticalburner-walls I-I form a floor on which the tiles are placed, thusbringing the tile in direct contact with the heat which comes up throughthe heat-spaces I.

The complete operation of my kiln is as follows: The tiles are placed onthe burner-walls, leaving space enough between them to allow the heat topass through. The fires in the upper and lower burners are started, thesmoke and gas passing upward to the top of the kiln,

from whence they escape. All of said fires are allowed to burn until Iobserve the watersmoke, at which time I weaken or strengthen my fires atsuch burners as I deem necessary until the kiln is properly burned.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. In a kiln having an open top, the combination, with the body of thekiln, a series of fines extended entirely across the bottom thereof andextended beyond its opposite ICO sides, of a series of burner-wallsarranged across the bottom of said kiln, disposed over and arrangedtransversely of the burners, and having communication therewith,substantially as and for the purpose described.

2. In a kiln, the combination, with a series 5 of burners [3, extendedlongitudinally across the bottom of the kiln, and a series of transverseburner-walls forming heat-spaces arranged over said burners andcommunicating; therewith, of heat deflectors 0r chambers 7,

in open at the top, arranged at opposite sides of the kilns transverselyover the burners 6, and a second series of burners 9 9, disposed overthe burners 6 and entering said transverse chambers 7, whereby a portionof the heat is led up on the sides of the kiln, substantially as de- 15scribed.
